To celebrate World Oceans Day on June 8, the National Science Foundation (NSF) interviewed biological oceanographer Mark Ohman and physical oceanographer Dan Rudnick of California's Scripps Institution of Oceanography about the El Niño effect. Ohman is the Lead Principal Investigator of the California Current Ecosystem (CCE) Long Term Ecological Research (LTER) program, which is investigating the California Current coastal pelagic ecosystem, with particular attention to the Pacific Decadal Oscillation and El Niño in altering the structure and dynamics of the pelagic ecosystem.

Among the questions asked of the scientists: how certain are we of the El Niño's arrival? How will we know it's here? What effect will it have on the weather, on coastal species, and on what's on our dinner tables?
